8c7da1d426 adapter: Rename functions and implement new functions, update test
We don't do calculations with different units (buffer offsets and bytes)
anymore but have functions for:
1) getting the number of bytes since the last discont
2) getting the offset (and pts/dts) at the last discont

and the previously added function to get the last offset and its distance from
the current adapter position.

67ae0ad225 adapter: Add methods to query current offset
API: gst_buffer_prev_offset
API: gst_buffer_get_offset_from_discont

The gst_buffer_get_offset_from_discont() method allows retrieving the current
offset based on the GST_BUFFER_OFFSET of the buffers that were pushed in.

The offset will be set initially by the GST_BUFFER_OFFSET of
DISCONT buffers, and then incremented by the sizes of the following
buffers.

The gst_buffer_prev_offset() method allows retrievent the previous
GST_BUFFER_OFFSET regardless of flags. It works in the same way as
the other gst_buffer_prev_*() methods.

41b85d91eb baseparse: add API for subclass to set tags
This is needed so that we can do proper tag handling
all around, and combine the upstream tags with the
tags set by the subclass and any extra tags the
base class may want to add.

API: gst_base_parse_merge_tags()

866f9ace5c adapter: Add get variants of the buffer based take functions
Main difference to gst_adapter_map() for all practical purposes is that
GstMeta of the buffers will be preserved.

86d7a597f0 bytereader: add gst_byte_reader_peek_sub_reader() and _get_sub_reader()
Adds API to get or peek a sub-reader of a certain size from
a given byte reader. This is useful when parsing nested chunks,
one can easily get a byte reader for a sub-chunk and make
sure one never reads beyond the sub-chunk boundary.

API: gst_byte_reader_peek_sub_reader()
API: gst_byte_reader_get_sub_reader()

Upgraded tests to check that the returned value is correct in the
_peek version

fa94322349 sparsefile: keep it private as helper API for downloadbuffer
There's no expectation that any other element or applications
might want to use this helper API any time soon, so keep it
private for the time being. There were open questions regarding
portability and binding-friendliness too.

This also removes the gio dependency of -base again.

581c4297d0 dataqueue: add gst_data_queue_push_force
Adds a variant of the _push function that doesn't check the queue limits
before adding the new item. It is useful when pushing an element to the
queue shouldn't lock the thread.

One particular scenario is when the queue is used to serialize buffers
and events that are going to be pushed from another thread. The
dataqueue should have a limit on the amount of buffers to be stored to
avoid large memory consumption, but events can be considered to have
negligible impact on memory compared to buffers. So it is useful to be
used to push items into the queue that contain events, even though the
queue is already full, it shouldn't matter inserting an item that has
no significative size.

This scenario happens on adaptive elements (dashdemux / mssdemux) as
there is a single download thread fetching buffers and putting into the
dataqueues for the streams. This same download thread can als generate
events in some situations as caps changes, eos or a internal control
events. There can be a deadlock at preroll if the first buffer fetched
is large enough to fill the dataqueue and the download thread and the
next iteration of the download thread decides to push an event to this
same dataqueue before fetching buffers to other streams, if this push
locks, the pipeline will be stuck in preroll as no more buffers will be
downloaded.
There is a somewhat common practice in dash streams to have a single
very large buffer for audio and one for video, so this will always
happen as the download thread will have to push an EOS right after
fetching the first buffer for any stream.

API: gst_data_queue_push_force

1681a1b1e0 dataqueue: add gst_data_queue_peek
This function works just like gst_data_queue_pop, but it doesn't
remove the object from the queue.

Useful when inspecting multiple GstDataQueues to decide from which
to pop the element from.

588cdcd369 libs: New growing-only queue.
This is a queue which has the same API as GQueue, except that:
* It uses an array, instead of a doubled-linked-list
* The array can only grow.

This code is not-threadsafe. It is up to the owner to make sure the
proper locking is taken before calling this API.

to wait for other things than EOS. Update the docs a little.
